This shouldn't come as a big surprise given Microsoft's Linux/open-source moves in the past couple of years, including joining the Linux Foundation and more, but their latest sponsorship comes down to joining the Open Source Initiative.

For squeezing maximum performance out of Linux systems with source-based workloads, most of you know there can often be tweaks to be had to the compiler stack for greater performance. As well with the never-ending advancements to the leading open-source code compilers, between releases can be measurable performance benefits but sometimes not without regressions too. With AMD's EPYC line-up still being very fresh and the underlying Zen microarchitecture (or "znver1" as referred to by the compiler toolchains), here are a variety of benchmarks under recent releases of the GCC and LLVM Clang compilers.

It's been one year since last testing BCache as a means in the Linux kernel's block layer to allow an SSD to serve as a cache for a larger but slower rotational hard drive. So I have carried out some fresh benchmarks using the Linux 4.14 Git kernel to provide not only fresh benchmarks of BCache but also MDADM SSD RAID on Linux and some other fresh SSD/HDD benchmarks.

I'm currently running some macOS 10.13 vs. Linux benchmarks for publishing within the next day or two on Phoronix. But so far in my macOS 10.12 Sierra vs. macOS 10.13 High Sierra benchmarks, what has stood out the most is the file-system performance due to HFS+ file-systems automatically being converted to the Apple File-System (APFS).

While Google Summer of Code ended one month ago, Jacob Lifshay has continued working on his "Vulkan-CPU" project now known as Kazan. He's certainly making progress on this CPU-based Vulkan implementation.

Besides the embargo expiring this morning on the Intel Core i9 7960X, the Core i9 7980XE Extreme Edition processor is also now fair game. Here is our look at the Linux performance for this 18 core / 36 thread processor within a single 165 Watt package.

While Intel previously announced the expanded Intel Core X-Series line-up including the Core i9 7960X and Core i9 7980XE processors, only today is the performance embargo expiring as these CPUs begin to ship to further battle AMD's Ryzen Threadripper line-up. Here is today's launch-day Linux benchmarks of the Core i9 7960X.

The annual X.Org Developers' Conference wrapped up on Friday as the meeting of key contributors to components including the xorg-server, Wayland, Mesa, and other crucial components of the Linux desktop stack.

Intel has rushed up the announcement of their 8th Gen Intel Core desktop processors following a recent leak. We can now confirm that these new Intel CPUs are en route to retailers, they have already arrived for testing, and will be benchmarked under Linux on Phoronix once that secondary embargo expires.

Earlier this year ASUS announced the Tinker Board as their first step into the ARM single board computer world. Earlier this month I finally received a Tinker Board for testing and it has been quite interesting to say the least. The Tinker Board with its Rockchip SoC has been among the most competitive ARM SBCs we have tested to date in its price range and the form factor is compatible with the Raspberry Pi.

DragonFlyBSD today picked up direct input support within the kernel's polling code. This can boost the networking performance though for now is just supported by the IX4 driver, what is used as the Intel 10Gb Ethernet driver.

A Norwegian developer has developed a new Qt platform abstraction plug-in to let Qt applications make use of GTK+ for windowing system integration. The Qt apps rely upon GTK+ as a host toolkit to provide GTK menus, GTK for input, and other integration bits.

While I usually look at the Linux kernel code size following each merge window, I am a few days late this time around due to busy Xeon/EPYC benchmarking and XDC2017. Anyhow, Linux 4.14 is showing some weight gains but nothing too bad.

Wrapping up our XDC2017 coverage for this annual X.Org developer event that took place this past week in Mountain View, Zhenyu Wang of Intel presented on their ongoing work for mediated GPU virtualization pass-through support on Linux, Intel GVT.

While NVIDIA isn't doing much to help out Nouveau, at least the company is contributing to the open-source Linux graphics ecosystem in other ways. In addition to presenting at XDC2017 this week on the Unix device memory allocator API and DeepColor / HDR support, they also presented on server-side GLVND.

SDL 2.0.6 was released on Friday as the latest feature update for this widely-used library that allows for more cross-platform portability of applications and games centered around input, audio, and video helpers.

Longtime Nouveau contributors Martin Peres and Karol Herbst presented at this week's XDC2017 X.Org conference at the Googleplex in Mountain View. It was a quick talk as they didn't have a whole lot to report on due to their open-source NVIDIA "Nouveau" driver efforts largely being restricted by NVIDIA Corp.

Earlier this year Keith Packard started a contract gig for Valve working to improve Linux's support for virtual reality head-mounted displays (VR HMDs). In particular, working on Direct Rendering Manager (DRM) and X.Org changes needed so VR HMDs will work well under Linux with the non-NVIDIA drivers.

It's been a few weeks since last delivering any large RADV/RadeonSI open-source AMD Linux graphics benchmark results due to being busy with testing other hardware as well as battling some regressions / stability problems within the AMDGPU DRM code and Mesa Git. But with Linux 4.13 stable and the newest Mesa 17.3-dev code, things are playing well so here are some fresh OpenGL vs. Vulkan benchmarks on three Radeon graphics cards.

While most of the talks that take place at the annual X.Org Developers' Conference are around the exciting progress being made across the Linux graphics landscape, at XDC2017 taking place this week at Google, the open-source GPGPU / compute talk is rather the let down due to the less than desirable state of the open-source OpenCL ecosystem.

Kevin Brace, the sole active developer left working on the OpenChrome driver stack for VIA x86 graphics, presented yesterday at XDC2017 about his work on this driver and how in the years to come he still hopes to work on other vintage GPU support.

Recently I wrote about a BFQ regression fix that should take care of a problem spotted in our recent I/O scheduler Linux 4.13 benchmarks while now that work has yielded a set of four patches working to improve this recently-merged scheduler.
